A small asteroid (mass of 150 g ) strikes a glancing blow at a satellite in empty space. The satellite was initially at rest and the asteroid was traveling at 2500 m/s . The satellite's mass is 140 kg . The asteroid is deflected 10 ∘ from its original direction and its speed decreases to 1200 m/s , but neither object loses mass. a.Determine the direction and of the satellite after the collision. Assume the initial direction of the asteroid...

Problem 1 An object of mass m1 travels through empty space at a constant speed until it strikes and sticks to a second object. As observed from the frame where the second object is motionless, the first object was traveling at a speed of vi. In that same frame, both objects travel at a speed of v after the collision. a. What is the general expression for the mass of the second object in terms of mi, vi, and v?...

An astronaut of mass 60 kg is on a space walk to repair a communications satellite when he realizes he needs to consult the repair manual. You happen to have it with you, so you throw it to him with a speed 4 m/s relative to the spacecraft. He is at rest relative to the spacecraft before catching the 3 kg book. Find (a) his velocity after catching the book (b) the initial and final kinetic energies of the book-astronaut...

Six artificial satellites circle a space station at constant speed. The mass m of each satellite, distance L from the space station, and the speed v of each satellite are listed below. The satellites fire rockets that provide the force needed to maintain a circular orbit around the space station. The gravitational force is negligible. 1. m=200kg,L= 5000 m, v=120 m/s 2. m=800kg,l= 10,000 m, v=40m/s 3. m=400kg,L= 2500 m, v=80m/s 4. m=100kg, L=2500 m, V=160m/s 5. m=300kg, L=10,000m, V=80...

Six artificial satellites circle a space station at constant speed. The mass m of each satellite, distance L from the space station, and the speed v of each satellite are listed below. The satellites fire rockets that provide the force needed to maintain a circular orbit around the space station. The gravitational force is negligible. Rank each satellite based on its period. Rank from largest to smallest. To rank items as equivalent, overlap them. 1. m=200kg,L= 5000 m, v=120 m/s...

A crate with a mass of 60 kg glides through a space station with a speed of 4.0 m/s. An astronaut speeds it up by pushing on it from behind with a force of 230 N, continually pushing with this force through a distance of 8 m. The astronaut moves around to the front of the crate and slows the crate down by pushing backwards with a force of 200 N, backing up through a distance of 6 m. After...

A robotic spacecraft is flying in interstellar space on a straight line with a constant speed of 77.6 km/s. (See figure.) This speed is measured with respect to the space station the spacecraft was originally launched from. In interstellar space the gravitational pull from the stars is negligible, because the stars are extremely far. The spacecraft turns its main rocket engine on for a time period of 6.9 hours. The rocket engine provides a thrust of 936 N of force....

A 507 kg satellite is in a circular orbit at an altitude of 754 km above a planet’s surface. This planet is similar to our Earth. Because of air friction, the satellite eventually is brought to the Earth’s surface, and it hits the Earth with a speed of 3 km/s. The radius of the planet is 7 × 106 m and its mass is 8 × 1024 kg. The gravitational constant is 6.67259 × 10−11 N m2 /kg2. How much...
